How much do hot tub heaters cost?

Hot tub heaters vary in price, depending on several factors, such as the brand, material quality, product specifications, and unique features. In most cases, you can expect to spend between $150 to $400 for a hot tub replacement heater. 

The good news is that spa heaters typically last a few years, so you don’t have to spend hundreds of dollars replacing your heater annually. Like spa jets, hot tub heaters don’t need to be replaced nearly as often as filters. 

What type of spa heater is best for a hot tub?

Choosing the right heater for a hot tub is important because some models are only suitable for specific types of hot tubs. You also have to consider the size of your hot tub and how much heating power it requires. It’s a good idea to shop for hot tub heaters of the same brand; that way, you know you’re looking at heaters that are compatible with your tub. 

When shopping for hot tub replacement parts, shopping according to your tub’s brand and model is the simplest way to ensure you’re buying the right parts. At Easy Spa Parts, you can filter hot tub heaters by brand, year, and model, allowing you to quickly identify the best fit for your spa or tub.

What is the lifespan of a hot tub heater?

Unlike hot tub filters that need to be replaced annually, hot tub heaters last a few years. Hot tub heaters have a lifespan of about three to five years, so you don’t have to worry about replacing yours. In fact, you don’t have to replace your hot tub heater as long as it functions correctly. Maintaining the proper chemical balance in your tub’s water can help you extend the life of your heater by preventing corrosion on the heating element.

If your hot tub is unable to maintain a warm, consistent temperature, it’s time for a heater replacement.

What size hot tub heater should I get?

Like hot tub covers, hot tub heaters vary from spa to spa. The best way to ensure you get the right parts for your hot tub is to check for a list of compatible models. When you shop at Easy Spa Parts, you can find a list of compatible models on every product page, so you know the parts you’re buying will fit specific tub models. 

Selecting the right size and model is important when looking for a hot tub heater. An underpowered heater will have a difficult time keeping your hot tub warm.
